What are some esoteric things that you think are stupid right now? Asking for a friend.

Mined about 100 on some old Radeon. Sold them at $30, because I thought they peaked. Trying not to think about that too much:)

Don't be too hard on yourself, it's next to impossible to guess which things are going to be transformational and which aren't. Look at some of the early early emails from Linus Torvalds on linux. In his mind the original linux kernel was just a cool toy that other devs could play around with. He invented linux and even he never saw it becoming the OS of practically the entire internet.
